How to set up the Technisat/B2C2 Flexcop devices
================================================

1) Find out what device you have
================================

Important Notice: The driver does NOT support Technisat USB 2 devices!

First start your linux box with a shipped kernel:
lspci -vvv for a PCI device (lsusb -vvv for an USB device) will show you for example:
02:0b.0 Network controller: Techsan Electronics Co Ltd B2C2 FlexCopII DVB chip /
 Technisat SkyStar2 DVB card (rev 02)

dmesg | grep frontend may show you for example:
DVB: registering frontend 0 (Conexant CX24123/CX24109)...

2) Kernel compilation:
======================

If the Flexcop / Technisat is the only DVB / TV / Radio device in your box
 get rid of unnecessary modules and check this one:
"Multimedia support" => "Customise analog and hybrid tuner modules to build"
In this directory uncheck every driver which is activated there
 (except "Simple tuner support" for ATSC 3rd generation only -> see case 9 please).
